摘要
Purpose: The finger grip and the palm grip are the most common needle holder grips for hand suturing in surgery. The major advantages of the palm grip are an increased versatility and the possibility to apply controlled force. However, there is a risk for a potential loss of precision and uncontrolled movement of the needle when disengaging the ratchet mechanism of the palmed instrument. The purpose of this study was to develop a new needle holder, referred to as the Frimand needle holder (FNH), and evaluate surgeons' perception of it. It was designed to overcome the above-mentioned disadvantages, hence facilitating palm and finger grip suturing. Moreover, we evaluated suture precision and attitudes related to the use of the finger grip and the palm grip. Methods: Thirty-two surgeons performed sutures utilizing both the palm grip and the finger grip on postmortem porcine skin and small bowels, comparing the FNH to a standard Crile-Wood needle holder (CWNH). The participants assessed the FNH on an evaluation form. Precision was determined by letting the surgeons perform 20 sutures utilizing the finger grip and the palm grip on a polyurethane pad with premarked insert and exit sites. The distance between the designated exit site and the real exit site defined precision and was measured with a digital sliding dimension scale. Results: We found that 28 (88%) of the 32 surgeons use the palm grip to some extent, and 31 surgeons (97%) experienced an advantage when suturing with the FNH using the palm grip. Twenty-four (75%) of the 32 surgeons would prefer to suture with the FNH instead of the CWNH. There was no significant difference in precision between the finger grip and the palm grip. Conclusion: This study presents a new needle holder facilitating palm grip suturing. A majority of the participants preferred the new FNH over the standard CWNH for hand suturing.
